Hello I am new in this forum.
I have a question of a Maxtor PCB swap. The broken disk is totaly dead. I want to test the broken pcb on an same type but working disk. The disk has the same firmware nr only the chipset nrs differ. I have made some pictures could a member check the pictures? and could you measere the pcb power output?
If the data is really important let professionals do it; I know quite something about electronics and am quite handy at soldering smd's and stuff; But I wouldn't dare doing it with my valuable stuff (Which is btw backupped a few times). Just think about how much the content of this disk is worth to you; Pro's will get your data back almost certainly. If you switch that PCB yourself you risk losing it alltogether...
Current Maxtor models require that you transfer "adaptive" data from your patient PCB to your donor. These data are stored in an 8-pin serial flash memory IC.
However, Maxtor models prior to Seagate's acquisition do not require such transfers. One only needs to match the PCB. In your case you need to match the PCBA (05A) and Code (TAH71DP0), which means that your boards are compatible.
As for differences in the chips, you need to understand that many chips which appear different are often functionally identical. For example, the two SDRAM chips are supplied by Micron Technology and Hyundai, but both will have the same capacity and pinout. The two DSPs look similar apart from the batch/date codes (?).
